diag-accounting-team

Overview​

  • Namespace: diag-accounting-team
  • Purpose: VAT Request Application - PRODUCTION
  • Age: ~410 days
  • Status: Active - Accounting/VAT management tool
  • Workloads: 1 deployment (1 replica)
  • Environment: PRODUCTION - Internal accounting tool

Architecture​

Simple single-deployment application for VAT request management:

  • vat-request--app--prod: Single application pod (1 replica)
  • ClusterIP Service: Internal access only

Auto-Scaling Configuration​

Not Applicable:

  • Single replica (no HPA configured)
  • Fixed 1 replica
  • Internal-only service

Access & Management​

View all resources:​

kubectl get all -n diag-accounting-team

Check pod status:​

# View pod
kubectl get pods -n diag-accounting-team

# View logs
kubectl logs -f deployment/vat-request--app--prod -n diag-accounting-team

# Check for errors
kubectl logs deployment/vat-request--app--prod -n diag-accounting-team --tail=100 | grep -i "error"

Access application:​

# Port forward for access
kubectl port-forward -n diag-accounting-team service/vat-request--app--prod 8080:80
# Access: http://localhost:8080

Restart service:​

kubectl rollout restart deployment/vat-request--app--prod -n diag-accounting-team

Monitoring​

Pod metrics:​

kubectl top pods -n diag-accounting-team

# Check resource usage
kubectl describe pod -n diag-accounting-team | grep -A 5 "Requests\|Limits"

Events:​

kubectl get events -n diag-accounting-team --sort-by='.lastTimestamp' | head -20

Application Workflow​

1. VAT Request Management​

  • Single application pod (1 replica)
  • Internal-only access (ClusterIP)
  • Accounting team tool
  • VAT receipt/invoice management

2. Access Pattern​

  • Internal service (ClusterIP)
  • No external LoadBalancer
  • Accessed via port-forward or internal ingress
  • Limited to accounting team users

Production Considerations​

High Availability​

Single Point of Failure:

  • 1 replica (No HA)
  • Pod restart = temporary unavailability
  • No redundancy

Recommendations​

  1. High Availability (Optional):

    • Current: 1 replica (acceptable for internal tool)
    • Low criticality: Accounting team tool
    • Consider 2 replicas only if downtime impacts business

  2. Backup Strategy:

    • Back up application data regularly
    • Document VAT request workflows
    • Export important records
    • Test restore procedures

  3. Monitoring:

    • Monitor pod health
    • Alert on pod failures
    • Track application errors
    • Monitor resource usage

  4. Access Control:

    • Internal only (ClusterIP)
    • Ensure proper authentication
    • Limit access to accounting team
    • Audit access logs

  5. Recent Update:

    • Pod updated 23 days ago
    • Stable operation
    • Monitor for issues post-update

Troubleshooting​

Application not accessible:​

# Check pod status
kubectl get pods -n diag-accounting-team

# Check service
kubectl get svc -n diag-accounting-team

# Test connection
kubectl port-forward -n diag-accounting-team service/vat-request--app--prod 8080:80
curl http://localhost:8080

# Check logs
kubectl logs -f deployment/vat-request--app--prod -n diag-accounting-team

Application errors:​

# Check pod logs
kubectl logs deployment/vat-request--app--prod -n diag-accounting-team --tail=100

# Check for errors
kubectl logs deployment/vat-request--app--prod -n diag-accounting-team | grep -i "error\|fail\|exception"

# Restart pod
kubectl rollout restart deployment/vat-request--app--prod -n diag-accounting-team

Performance issues:​

# Check resource usage
kubectl top pod -n diag-accounting-team

# Check pod events
kubectl describe pod -n diag-accounting-team

# Check resource limits
kubectl describe deployment vat-request--app--prod -n diag-accounting-team | grep -A 10 "Limits\|Requests"

Performance Metrics​

Current Scale​

  • Deployment: 1 replica
  • Age: ~410 days (stable)
  • Recent Update: 23 days ago
  • Access: Internal only (ClusterIP)

Stability​

  • Pod Age: 23 days (recent update)
  • Restarts: Check with kubectl get pods -n diag-accounting-team
  • Purpose: Internal accounting tool
  • Single Point of Failure: Yes (1 replica)

Architecture Notes​

  • Simple Deployment: Single pod application
  • Internal Access: ClusterIP service only
  • Accounting Tool: VAT request management
  • No HA: Single replica acceptable for internal tool
  • Low Traffic: Accounting team usage only
  • Stable: 410 days old with recent updates
